The switching device 100 controls the power supply side and the load side connection lines L1 and L2 to selectively conduct or disconnect each other according to the operation of the operation knob 60 provided at the upper portion of the upper lid 20. [ . In this case, the power source side connection line (L1) means an electric wire connected to a power source, and the load side connection line (L2) is an electric wire connected to an electric device.

At this time, the switching device 100 may be provided as a pair between the power source and the electric device. That is, the power source side connection line connects the power source and the electric device, and the load side connection line connects the pair of switching devices, respectively. One end side of the load side connection line may be selectively connected according to the operation of each switching device so that the electric device may be powered or disconnected. That is, the power of the power source device may be turned on by operating the one side switching device, and the power source of the electric device may be turned on by operating the other side switching device.

The case 10 is formed with a plurality of insertion holes 12 through which the power supply side and the load side connection lines L1 and L2 are inserted, A space k is formed.

The width in the forward and backward direction means the width of the case 10 in a rectangular shape as a whole. The width of the mounting space k in the case portion 10 of the present invention in the front- The width can be reduced to 50% or less. In the present invention, the structure of each component part in which the width in the front-rear direction of the mounting space k can be reduced to 50% or less of the conventional width is disclosed.

In detail, the case 10 is made of an insulating material and an internal combustion material so that the short-circuit between internal components and internal currents can be prevented from leaking to the outside. In addition, the component part may be provided with a predetermined rigidity so that the component parts can be installed at a predetermined position, and the partition space for mounting and fixing the component parts may be formed in the mounting space k. For example, the case 10 may be made of a synthetic resin material such as polycarbonate, polyethylene, and polyvinyl chloride, and may be made of a known insulating synthetic resin material As shown in FIG. Here, the component parts are preferably understood as the terminal part t, the light emitting circuit part 70, the elastic contact piece 80, and the puller 90, which will be described later.

The insertion holes 12 are formed on one side of the case part 10 in a forward and backward direction and on the other side of the case part 10 in a pair of spaced- And may be formed at four places on the lower surface. A pair of insertion holes 12 spaced apart from each other in the forward and backward directions of the case part 10 are formed in one insertion hole 12 and a pair of insertion holes 12 spaced apart in the other forward and backward direction are inserted in the other insertion hole 12 12).

Here, the power source side connection line L1 is inserted into at least one of the one side insertion holes 12, and the load side connection line L2 is inserted into at least one of the other side insertion holes 12. [ Of course, a separate load side connection line may be inserted into each insertion hole 12 formed as a pair of the other sides.

In addition, it is preferable that a plurality of coupling holes 11 are formed along the opened upper edge of the case part 10. The engaging portion 23 of the upper lid 20 is hooked to the engaging hole 11 so that the case 10 and the upper lid 20 are assembled together . At this time, the coupling holes 11 are formed in the side wall portions on the front and rear sides of the opened upper edge, and may be formed to correspond to the positions where the insertion holes 12 are formed.

On the other hand, the terminal portion (t) is accommodated in the mounting space (k). At this time, the terminal portion t preferably includes a movable elastic terminal 50, a base terminal 40, and a switching terminal 30.

Specifically, the movable elastic terminal 50 is disposed at a central portion of the mounting space k, and seesaw motion is selectively performed according to the operation of the operation knob 60 provided on the case portion 10. The base terminal 40 supports a seesaw motion of the movable elastic terminal 50 and has a first contact surface 34a contacting an end of the power source side connection line L1 at an end portion extending to one side of the mounting space k, A portion 41 is formed. The switching terminal 30 is provided on the other side of the mounting space k and is selectively energized with the base terminal 40 during seesaw motion of the movable elastic terminal 50, A second contact surface portion 31 is formed which is in contact with the end portion.

At this time, the operation knob 60 includes a locker portion 62 extended to correspond to both sides of the case portion 10 and a movable protrusion 63 protruding downward from the center of the lower surface of the locker portion 62 Quot; T " shape as a whole. A hinge portion 62a is formed on the front and rear surfaces of the locker portion 62 so as to be hinged to the upper lid portion 20 described later.

At this time, the movable protrusion 63 is arranged to contact one side of the movable elastic terminal 50 through the movable stator bore 21a formed in the upper surface of the upper lid 20. [ That is, the movable elastic terminal 50 is pressed against the end of the movable protrusion 63 and is seesawed in a symmetrical manner with respect to the direction in which the locker portion 62 seesaw. In addition, a button cover (not shown) is coupled to the upper surface of the locker portion 62 to improve the appearance and operation feeling of the product.

On one side of the base terminal 40, a seesupport 43 is disposed at the center of the mounting space k and contacts a lower portion of the movable elastic terminal 50 to support a seesaw motion.

The power supply side connection line L1 inserted through the one side insertion hole 12 is formed in an end portion of the connection portion 42 integrally extending from one end of the seesupport portion 43 to one side of the mounting space k. And the first contact surface portion 41 is in contact with an end portion of the first contact surface portion 41. [

At this time, the connection part 42 is extended to be supported on the inner surface of the case part 10, and the first contact surface part 41 is disposed corresponding to the passing direction of the one side insertion hole 12. Accordingly, the contact area between the first contact surface portion 41 and the outer circumferential surface of the end portion of the power source side connection line L1 increases, so that current can be stably supplied.

The switching terminal 30 has a terminal connection portion 30 extending integrally from the end portion of the second contact surface portion 31 disposed in correspondence with the passing direction of the other insertion hole 12 toward the center portion of the mounting space k, (Not shown). Since the second contact surface portion 31 is disposed corresponding to the penetration direction of the other insertion hole 12, the area of contact with the outer circumferential surface of the end portion of the load side connection line L2 is increased and the current is stably energized .

In this case, the switching terminal 30 may be provided so as to be alternately contacted with the movable elastic terminal 50 during the seesaw motion of the movable elastic terminal 50. However, in the present invention, the single switching terminal 30 is provided in the movable elastic terminal 50, It is preferable to provide a single structure that can be energized or disconnected during seesaw motion of the vehicle.

The movable elastic terminal 50 is provided with a seesaw groove portion 52 hinged to the upper end of the seesaw support portion 43. The seesaw groove portion 52 stably supports the upper edge of the seesaw support portion 43 It is preferable to form the groove concave upward. As the upper rim of the seesupport portion 43 is inserted into the seesaw groove portion 52 while the movable elastic terminal 50 is pressed by the movable protrusion 63, It is possible to prevent slippage of the movable member 50. Further, since the outer surface of the end portion of the seesaw support portion 43 is in contact with the concave inner surface of the seesaw groove portion 52, the contact area between the terminals can be maintained stably.

Here, it is preferable that the terminal contact portion 51 extends integrally from the seesaw groove portion 52 toward the other side of the mounting space k. That is, the end of the terminal contact portion 51 is opposed to the end of the terminal connection portion 32 of the switching terminal 30, and when the movable elastic terminal 50 is seated, the terminal contact portion 51, (32) are contacted with each other.

At this time, it is preferable that the elastic portion 53 is provided from the seesaw groove portion 52 to one side of the mounting space k so that the seesaw motion of the movable elastic terminal 50 is resiliently supported. Here, the elastic portion 53 is bent so as to extend to one side of the mounting space k and have an end side opposed to the upper side of the seesaw groove portion 52.

That is, since the bent elastic portion 53 elastically supports between the movable protrusion 63 and the seesaw groove 52 of the operation knob 60, a click feeling is given during operation of the operation knob 60 do. Accordingly, the operation knob 60 and the movable elastic terminal 50 can be clearly seamed, and the seated state can be stably pressed and held.

The elastic portion 53 provides a elastic restoring force to push the movable protrusion 63 between the end portion of the movable protrusion 63 and the seesaw groove portion 52 in a state where the movable elastic terminal 53 is rotated. Therefore, even if the external force applied to the operation knob 60 disappears, the state in which the movable projection 63 is rotated to one side or the other side can be fixed and maintained.

Here, a restricting round portion 53a may be formed at the end of the elastic portion 53 so that the end of the movable protrusion 63 is inserted and constrained to be downwardly rounded. At this time, the constraining round portion 53a may be formed to extend in both directions of the seesaw groove portion 52 along a portion opposed to the upper portion of the seesaw groove portion 52. Thus, even when the operation knob 60 is repeatedly operated, the end portion of the movable projection 63 can be stably rotated without being separated from the elastic portion 53. [

The terminal contact portion 51 is elastically resiliently fixed between the contact groove portion 52 and the terminal contact portion 51 during seizure movement of the movable elastic terminal 50 A curved elasticity reinforcing portion 54 may be further formed.

In detail, the elastic reinforcing portion 54 is provided in a zigzag fashion in the vertical direction along the extension direction of the terminal contact portion 51. [ Therefore, the state in which the terminal contact portion 51 is in close contact with the terminal connection portion can be more stably maintained for a long period of time by the elastic deformation and the restoring force of the elastic reinforcement portion 54.

Accordingly, even if the width of the components constituting the terminal portion (t) is narrowed corresponding to the narrow mounting space (k) for the compactness of the switching device (100), the contact force between the terminals is maintained, Which can be provided to the user. Further, since the thickness of each side wall of the case part 10 can be maintained while the front and rear widths of the case part 10 itself are reduced, the insulation performance and durability are improved, Can be significantly improved.

Accordingly, the compatibility of the product can be remarkably improved by increasing the degree of freedom of design change, and a compact product in which the space efficiency at the time of installation can be improved through the design change to reduce the front-rear width of the case part 10 have.

The upper end of the first contact surface portion 41 and the second contact surface portion 31 may be formed with a restricting surface portion 31a bent to face the insertion hole 12. [ As a result, the area where the coupling portion 23 is in close contact with the base terminal 40 and the switching terminal 30 is increased, so that it can be more stably pressed and fixed. The engaging portion 23 is in close contact with the base terminal 40 and the switching terminal 30 so as to substantially face the upper ends of the first contact surface portion 41 and the second contact surface portion 31 It is desirable to understand it.

In addition, the insertion depth can be limited by engaging the ends of the power source side and load side connection lines (L1, L2) with the inner surface of the restricting surface portion 31a. As a result, it is possible to prevent a safety accident such as a malfunction or short-circuit due to the excessive connection of the connection lines L1 and L2 and contact with neighboring components.

Of course, each of the connection lines L1 and L2 may be in contact with the end of the coupling portion 23 to limit the insertion depth.

Specifically, the engaging portion 23 is extended so as to simultaneously press and fix the respective contact surface portions 31, 41 and the elastic contact piece 80, which are disposed on opposite sides of the respective connection lines L1, L2. When the case 10 and the upper lid 20 are assembled together, the terminal portion t and the elastic contact piece 80 are simultaneously pressed and fixed by the engaging portion 23, It is possible to restrict the insertion depth of the first and second guide plates L1 and L2 to maintain a more stable assembled state.

At this time, the movable elastic terminal 50, the base terminal 40, and the switching terminal 30 may be made of a metal material such as brass or copper having high conductivity so that the electrical resistance is reduced in a state of being in contact with each other. Furthermore, the movable elastic terminal 50 may be made of a brass material having high conductivity and excellent elasticity. In addition, each of the terminals 30, 40, 50 can be formed into each of the above-described shapes as a single metal plate is integrally cut and bent. In addition, connection protrusions may be provided at the ends of the terminal contact portion 51 and the terminal connection portion 32 to improve the force so as to closely contact each other.

Here, the first contact surface portion 41 and the second contact surface portion 31 may be formed in a state in which the base terminal 40 and the switching terminal 30 are disposed on both sides of the mounting space k, And a length corresponding to a lower edge of the lower surface 11 of the body 11. In addition, it is preferable that an end portion of the engaging portion 23, which will be described later, is downwardly extended to a length corresponding to the lower edge of the engaging hole 11.

Accordingly, when the coupling portion 23 is coupled to the coupling hole 11, the end of the coupling portion 23 contacts the base terminal 40 and the switching terminal 30, that is, the first contact surface portion 41, And the upper side of the second contact surface portion 31, as shown in Fig. The state in which the base terminal 40 and the switching terminal 30 are disposed inside the mounting space k is stably fixed in the repetitive operation of the switching device 100, Can be prevented.

Meanwhile, the upper lid part 20 may be provided to cover the upper side of the case part 10. The upper lid part 20 covers the upper side of the mounting space k and extends from the lower surface of the body part 21 formed below the outer cross sectional area of the case part 10, Downward. That is, the upper lid portion 20 has a cross-sectional area of the mounting space k, that is, a cross-sectional area on the inner circumferential side of the opened upper rim of the case portion 10, .

Therefore, when the upper lid part 20 is coupled to the upper side of the case part 10, the upper lid part 20 can be protected by the upper lid part 20 outside the side wall part of the case part 10 while protecting the component parts accommodated in the mounting space k. (20) are not protruded. Accordingly, the width of the switching device 100 in the front-rear direction can be made compact, and the gap between the adjacent switching devices 100 is not substantially generated. Thus, space utilization can be remarkably improved because a maximum number of switching devices 100 are installed in a limited space of the standardized housing (1 in FIG. 7).

In this case, the body portion 21 is provided with a lamp through hole (not shown) through which the light emitted from the movable protrusion penetration portion 21a through which the movable protrusion 63 passes, and the lamp portion 76 of the light emitting circuit portion 70 (21b) is formed. Here, a hinge fastening portion 22 is formed in the front-rear direction rim of the movable projection penetrating portion 21a, to which the hinge portion 62a of the operation knob 60 is fastened.

The engaging portion 23 may be provided at a position corresponding to the engaging hole 11 formed in the case portion 10 and may include an alignment extending portion 25 and a hook projection 26 Do. Here, the alignment extension portion 25 has an outer surface portion corresponding to the inner surface portion of the mounting space k and an end portion extending to be opposed to the upper end portion of the terminal portion t. The hook protrusion 26 is protruded in the outward direction of the alignment extension 25 so as to be hooked to the inside of the coupling hole 11. [

 At this time, it is preferable that the upper lid part 20 is made of a synthetic resin material having high rigidity and insulation and capable of a predetermined elastic deformation. Therefore, when the upper lid part 20 is coupled to the upper side of the case part 10, the alignment extension part 25 can be resiliently deformed inward by the projected thickness of the hook projection 26 . When the hook protrusion 26 is disposed to correspond to the inside of the coupling hole 11, the hook extension 26 is elastically restored to the inside of the coupling hole 11, As shown in Fig.

The hook protrusion 26 is formed so that the hook protrusion 26 is gradually overlapped with the outer surface of the alignment extension 25 so that the hook protrusion 26 is engaged with the upper edge of the coupling hole 11. Therefore, when the upper lid part 20 is coupled to the upper side of the case part 10, the lower surface of the hook projection 26 slides in contact with the opened upper edge of the case part 10.

As a result, the upper lid part 20 can be easily assembled with only one touch of pushing the upper lid part 20 to the bottom side of the case part 10, and excessive shrinkage deformation of the alignment extending part 25 is prevented, have. Further, the upper portion 26a side of the hook projection 26 is stepped and fixed to the upper edge of the coupling hole 11. Therefore, it is possible to prevent the upper lid part 20 and the case part 10 from being separated arbitrarily in the assembled state.

Here, it is preferable that the coupling portion 23 is located at four positions corresponding to the front end and the rear end of the base terminal 40 and the switching terminal 30, respectively. At this time, the alignment extension portion 25 extends so that the end portion 25a corresponds to the lower edge of the coupling hole 11, and the hook projection 26 has a width corresponding to the inner width of the coupling hole 11, It is preferable that the thickness be corresponding to or less than the thickness of the part. Accordingly, even if the hook projection 26 is inserted into the coupling hole 11, it can be prevented that the hook projection 26 protrudes outside the side wall of the case part 10.

When the hook protrusion 26 is inserted into the hook hole 11 and hooked to the hook hole 11, the first contact surface portion 41 of the base terminal 40 is connected to the end portion 25a of the alignment extension portion 25, And the upper end of the second contact surface portion 31 of the switching terminal 30 are pressed and fixed.

Further, as the engaging portion 23 is inserted into the case 10, the portion protruding outside the side wall of the case 10 is substantially removed, so that the width of the switching device 100 in the front- Can be significantly reduced. In addition, since a plurality of switching devices 100 can be closely disposed on the inside of the housing (1 in Fig. 7) without any gap, the number of switching devices 100 that can be installed in the same space can be increased. Accordingly, it is possible to provide the switching device 100 which is more compact and maximizes the installation space efficiency.

The conductive contact piece 80 of conductive material elastically presses the power supply side and the load side connection lines L1 and L2 toward the first contact surface portion 41 and the second contact surface portion 31, respectively. That is, the end portions of the connection lines L1 and L2 are inserted between the first contact surface portion 41 and the second contact surface portion 31 and the elastic contact pieces 80 disposed adjacent to the first contact surface portion 41 and the second contact surface portion 31, 80 press the end portions of the connection lines L1, L2 toward the first contact surface portion 41 and the second contact surface portion 31, a stable connection state can be maintained.

Each of the engaging portions 23 extends downward to a length that presses and fixes the first contact surface portion 41 and the upper end portions of the second contact surface portion 31, It is preferable to expand on both sides with a width to be pressed and fixed by being in contact with the outwardly curved outer surface of the base plate 80.

The first elastic portion 81 extends from one end of the base portion 84 to a center portion of the mounting space k and the second elastic portion 82 extends from the base portion 82 (K) outwardly of the upper end portion of the mounting space (k). At this time, a flat surface portion 83 parallel to the bottom surface of the mounting space k may be formed at the end of the second elastic portion 82.

That is, the resilient contact piece 80 may be plastically deformed into an S-shape as a whole, and may be disposed in the one-side insertion hole 12 and the other-side insertion hole 12, have. At this time, the elastic contact pieces 80 may be provided symmetrically in pairs in correspondence with the pair of one side and the other side insertion holes 12. The ends of the first elastic portion 81 for pressing the end portions of the power supply side and the load side connection lines L1 and L2 are inserted between the pair of elastic contact pieces 80 by the contact surface portions 31 and 41, A puller 90 may be provided.

Here, the first elastic portion 81 is plastically deformed in an upwardly inclined manner about the rounded first bent portion 80a, and the end portion is extended adjacent to the respective contact surface portions 31 and 41. It is preferable that an end portion of the first elastic portion 81 and the contact surface portions 31 and 41 are formed to be narrower than the end diameters of the connection lines L1 and L2.

Therefore, the first elastic portion 81 is formed so that the first bent portion 80a is supported by the inner surface of the bottom side of the mounting space k, and the connection line L1 inserted through the insertion hole 12 , L2) in both directions. When the insertion of the connection lines L1 and L2 is completed, the ends of the connection lines L1 and L2 can be pressed toward the respective contact surface portions 31 and 41 by elastic restoring force. Accordingly, since the connection lines L1 and L2 and the contact surface portions 31 and 41 are in intimate contact with each other, the current driven by the switching device 100 can be stably energized.

The second elastic portion 82 is plastically deformed in a state of being bent upward in a diagonal direction with respect to the first elastic portion 81 about the rounded second bent portion 90b. At this time, when the elastic contact pieces 80 are arranged on both sides of the mounting space k, the second elastic parts 82 are bent at an angle corresponding to the inside of the rims of the respective engagement holes 11 desirable.

Accordingly, when the case 10 and the upper lid 20 are assembled, the engaging portion 23 is hooked to the engaging hole 11, The outer peripheral surface of the elastic portion 82 is fixed while being pressed downward. Accordingly, the elastic contact pieces 80 can be prevented from flowing even when the switching device 100 is assembled or when the connection lines L1 and L2 are separated from each other using the puller 90.

That is, the engaging part 23 protruding to mediate coupling between the case 10 and the upper lid 20 prevents the base terminal 40 and the switching terminal 30 from flowing And performs a triple function of fixing the elastic contact piece 80. Accordingly, the leakage or contact failure due to the flow of the component accommodated in the mounting space k can be prevented, and the safety of the switching device 100 can be remarkably improved.

Since the supporting means for fixing the terminal portion t and the elastic contact piece 80 to the case 10 to the upper lid 20 are not complicated, the shape of each component is simplified and minimized .

Thus, the terminal space t and the elastic contact pieces 80 can be accommodated in the narrowed mounting space k as much as possible. Therefore, since the size of each component for stable operation of the switching device 100 can be optimized, the driving safety can be improved. In addition, the shape of the case 10 and the upper lid 20 can be simplified, which significantly reduces the incidence of defects during manufacture and can significantly improve the productivity and economy of the product by reducing manufacturing costs.

At this time, the elastic contact piece 80 has an elastic force capable of pressing each of the connection lines L1 and L2 toward the respective contact surface portions 31 and 41, and also, through the respective connection lines L1 and L2, And the like. For example, the elastic contact piece 80 may be made of stainless steel, and may be made of a brass or copper material, such as the terminal portion t described above.

The elastic contact pieces 80 are bent in an S shape so as to provide an elastic force to press the connection lines L1 and L2 and a terminal terminal 72 described below. As a result, the consumption of raw materials to be used can be remarkably reduced, and the number of manufacturing operations can be simplified, so that the productivity can be remarkably improved.

Further, in the elastic contact piece 80, the outer circumferential surface of the second elastic portion 82 is press-supported to the outer end 23a of the engaging portion 23. Therefore, the direction in which the elastic restoring force is provided about the bent portions 80a and 80b can be concentrated on the first elastic portion 81 that substantially presses the connection lines L1 and L2. As a result, the contact portions 31 and 41 and the respective connection lines L1 and L2 are more reliably supported by the engaging portion 23 even in a bent shape minimized than the conventional elastic piece And can be stably contacted.

In addition, since the space in which the elastic contact piece 80 is deformed or restored is limited between the inner bottom surface of the mounting space k and the engagement hole 23, excessive deformation of the elastic contact piece 80 is prevented, Resilience may be maintained for a long time.

Meanwhile, a light emitting circuit part 70 may be further included between the upper lid part 20 and the terminal part t. Here, the light emitting circuit portion 70 includes a substrate portion 71 and a terminal terminal 72.

In detail, the base portion 71 has a penetrating portion 71a communicating with the movable protuberance hole 21a at a central portion thereof and communicating with the movable protuberance 63. A wiring 73 is printed on the upper surface of the substrate 71. A ramp portion 76 is provided on one side of the wiring 73 and a current passing through the wiring 73 is provided on the other side. A resistor portion 75 is provided.

The terminal terminal 75 is fastened to the terminal fastening part 74a formed at both ends of the wiring 73 so as to receive a current to be energized along the power supply side and the load side connection lines L1 and L2. At this time, the terminal terminal 75 is bent outward in both lateral directions so that the one end portion 72a is opposed to the flat surface portion 83 of the elastic contact piece 80. [

That is, when the bent one end portion 72a of the terminal terminal 72 and the flat surface portion 83 are disposed to face each other, the electric current passing through the power supply side and the load side connection lines L1 and L2 becomes the elasticity And may also be transmitted to the light emitting circuit part 70 through the contact piece 80. [

At this time, a pressing rib portion 24 is formed on the lower surface of the upper lid portion 20 so as to press-contact the bent one end portion 72a of the terminal terminal 72 and the flat surface portion 83 .

Specifically, the pressurizing ribs 24 are formed at both ends of the lower surface of the upper lid portion 20, preferably at positions corresponding to both sides on which the elastic contact pieces 80 are disposed. The pressing rib portion 24 may extend in correspondence to the thickness of the substrate portion 71 and the gap between the terminal terminals 72 protruding to the lower side of the substrate portion 71.

When the upper lid portion 20 is coupled to the upper side of the case portion 10, the bent end portion 72a of the terminal terminal 72 is bent downward by the end of the pressurizing rib portion 24 Lt; / RTI >

The resilient contact piece 80 is elastically resiliently restored in the upward direction by the second resilient part 82 having the second resiliently deformed center point 80b of the resilient contact piece 80, The surface contact of the flat surface portion 72a and the flat surface portion 83 can be more stably supported. The second elastic portion 82 is pressed and supported by the outer end 23a of the engaging portion 23 so that the bent one end portion 72a of the terminal terminal 72 is excessively pressed Can be prevented.

At this time, the flat surface portion 83 is bent substantially at the bending point formed on the end side of the second elastic portion 82 and is provided substantially parallel to the bottom surface of the mounting space k. Therefore, since the area of surface contact between the flat surface portion 83 and the bent one end portion 72a of the terminal terminal 72 is maximized, the current can be stably supplied.

That is, the resilient contact piece 80 has a pressing force for stably contacting the contact surface portions 31 and 41 and the connecting lines L1 and L2 and a pressing force for making stable contact with the terminal terminal 72 simultaneously . At the same time, since the current passing through the terminal portion (t) is utilized as one terminal capable of transmitting the current to the light emitting circuit portion (70), more than one function can be provided by one component. Therefore, even if the mounting space k is formed narrowly like the switching device 100 of the present invention, the fixation force and the adhesion force between the respective components can be improved and stably operated.

The base terminal 40 and the switching terminal 30 extend to a position corresponding to one end of the terminal terminal 72 in order to transmit a current to the light emitting circuit unit 70. [ Alternatively, the present invention may be formed with a minimum length for mutual contact of the respective switching terminal 30, the base terminal 40 and the terminal terminal 72. Thus, the manufacturing cost and the material consumption for manufacturing the respective component parts are remarkably reduced, so that the productivity and the economical efficiency can be remarkably improved.

The light emitting circuit portion 70 is formed with a fastening hole 71b through which the coupling portion 23 passes so that the end of the coupling portion 23 is disposed opposite to the upper side of the terminal portion t. On the front and rear surfaces of the upper lid portion 20, stepped groove portions 27 recessed inwardly are formed so that the inner surfaces of the grooves are continuous with the outer surface portion of the engaging portion 23.

Here, the light emitting circuit portion 70 may be pressed and constrained to the bottom surface of the stepped groove portion 27 by the upper surface of the fastening hole 71b. In detail, the sectional thickness of the stepped groove portion 27 is set to be substantially equal to the thickness of the body portion 21 so as to stably cover constituent parts provided therein while minimizing material consumption for manufacturing the upper lid portion 20 Respectively. Therefore, the stepped groove portion 27 is recessed inwardly, and the inner surface thereof is convexly protruded toward the inner space side of the body portion 21. Accordingly, the bottom surface of the stepped groove 27 can overlap the edge of the fastening hole 71b (hatched portion 27a in FIG. 4).

Accordingly, the light emitting circuit unit 70 is restrained between the terminal portion t pressed and fixed to the end portion of the engaging portion 23 and the bottom portion of the stepped groove portion 27 to prevent the flow. This prevents the position of the light emitting circuit part 70 from being changed when the switching device 100 is assembled or installed and the terminal terminal 71 pressed by the pressing rib part 24 is pressed against the substrate part 71, Can be prevented.

Furthermore, the outer surface of the stepped groove portion 27 is formed in a substantially continuous profile with the outer surface portion of the engaging portion 23. [ Even if the alignment extension 25 is resiliently deformed by the protruded thickness of the hook projection 26 when the upper lid part 20 is coupled to the upper side of the case part 10, It is possible to prevent cracks and deformation from occurring at the lower boundary of the lower surface of the substrate.

It is also easy to pull the mold for forming the protruding shape of the hook projection 26 along the continuous profile of the stepped groove portion 27 and the engaging portion 23. Therefore, the production of the upper lid part 20 through injection molding is facilitated, and the productivity may be significantly improved.

That is, in the switching device 100 of the present invention, only when the upper lid part 20 and the case part 10 are engaged, the terminal part t and the elastic contact piece 80 are separated by the engaging part 23 And the light emitting circuit portion 70 can be pressed and restrained to the bottom portion of the stepped groove portion 27. [ Therefore, even if the shape of each component is simplified / minimized so that the switching device 100 is formed compactly, the operation stability can be remarkably improved because each component has a combined function for coupling and fixing.

6A and 6B illustrate driving states of the switching device 100 according to an exemplary embodiment of the present invention.

6A and 6B, when one side of the button cover (not shown) or the locker portion 62 is pressed, the movable protrusion 63 is rotated to the other side of the mounting space k. The connection between the movable elastic terminal (50) and the switching terminal (30) is switched as the movable elastic terminal (50) is seesawed by the movable projection (63).

At this time, the seesaw center of the movable elastic terminal 50 and the rotational center of the operation knob 60 are preferably arranged on the same vertical line (v). The seesaw center of the movable elastic terminal 50 is a contact portion between the seesupport 43 and the seesaw groove 52. The center of rotation of the operation knob 60 is connected to the hinge joint 22, It is preferable that the hinge portion 62a is understood.

That is, as the contacts of the movable elastic terminal 50 and the movable protrusion 63 are moved to one side and the other side of the vertical line (v), the movable elastic terminal (50) is seesawed. Furthermore, since the movable protrusion 63 is formed in a wedge shape having a narrowed end, the seesaw motion of the movable elastic terminal 50 can be accurately operated during the rotational movement of the movable protrusion 63.

The movable elastic terminal 50 may be selectively connected to the switching terminal 30 as it is contacted with and supported by one side of the base terminal 40 and seesaw motion. Accordingly, the base side terminal 40, the movable elastic terminal 50, and the switching terminal 30 are energized, so that the power source side connection line and the load side connection line can be energized.

6A, when one side of the operation knob 60 is operated to be lowered, the movable protrusion 63 is rotated to the other side on the vertical line v, thereby pressing the movable elastic terminal 50. As shown in FIG. The other end of the movable elastic terminal 50 is lowered so that the terminal contact portion 51 and the terminal connection portion 32 of the switching terminal 30 are brought into contact with each other to energize the current and are connected to the switching device 100 Electric current is applied to the electric device.

At this time, a current passing through each of the connection lines L1 and L2 is also transmitted to the light emitting circuit unit 70 through the elastic contact piece 80 made of a conductive material. That is, the electrical device and the light emitting circuit unit 70 are connected in a substantially parallel connection state.

The light emitting circuit part 70 is provided with the resistor part 75 so that the electric current is supplied to the switching terminal 30, the movable elastic terminal 50 and the base terminal 40, do. Accordingly, the electric device is driven by receiving the current, and the light emitting circuit unit 70 is maintained in the off state.

6B, when one side of the operation knob 60 is operated to be elevated, the movable protrusion 63 is rotated to one side on the vertical line v to press the movable elastic terminal 50. Accordingly, the other side of the movable elastic terminal 50 is raised, and the terminal contact portion 51 and the terminal connection portion 42 are separated from each other, so that the flow of current to the electric device is interrupted.

Although the switching terminal 30 and the movable elastic terminal 50 are spaced apart from each other and the electric current is cut off, the light emitting circuit portion 70 is electrically connected to the ends of the connection lines L1 and L2 by the elastic contact pieces 80, As shown in FIG. Therefore, the light emitting circuit unit 70 may be connected in a substantially series connection with the power source. The lamp unit 70 is turned on because the current from the power source is substantially transmitted to the light emitting circuit unit 70 and the lamp unit 70 is turned on through the lamp through hole 21b formed in the upper lid unit 20, The light irradiated from the lamp unit 70 is passed. Accordingly, since the off state of the switching device 100 can be visually confirmed, the usability can be remarkably improved.

The resistive part 75 may block the current applied through the resilient contact piece 80 when the switching terminal 30 and the movable elastic terminal 50 are in contact with each other, It is preferable that the current applied in a state where the movable elastic terminal 50 is spaced apart is formed to have a resistance value to be energized.

Therefore, it is possible to prevent the lamp unit 76 from being turned on in a state where the switching terminal 30 and the movable elastic terminal 50 are in contact with each other, thereby unnecessarily turning the switching apparatus 100 off or on Can be prevented. Further, unnecessary use of the electric device connected to the switching device 100 is minimized by visually confirming the ON / OFF state of the lamp part 76, thereby preventing power consumption.

In addition, since the lamp unit 70 is provided to irradiate a light source having a predetermined wavelength, the on / off state of the switching device 100 can be easily determined regardless of the brightness of the space in which the switching device 100 is installed have.

Meanwhile, FIG. 7 is an exemplary view showing a housing to which the switching device 100 according to an embodiment of the present invention is applied.

As shown in FIG. 7, the switching device 100 may be designed to have a front-to-rear width of about 1 cm, which is about 50% smaller than that of a conventional switching device having a front-back width of about 2 cm. Therefore, six switching devices 100 can be installed in one domestic standard housing 1 having a front space width of about 7 cm in the installation space.

Accordingly, since the switching device 100 capable of on / off operation of a plurality of electric devices can be installed in the standardized housing 1 as much as possible, space utilization and interior aesthetics can be remarkably improved.

The engaging portion 23 protruded to fasten the case 10 and the upper lid 20 is inserted into the mounting space k so that the gap between the switching devices 100 is minimized, The terminal portions t and the upper ends of the elastic contact pieces 80 are opposed to each other so as to be pressed and fixed at the same time. Accordingly, since the engaging part 23 protruding for assembling the parts simultaneously supports the terminal part t and the elastic contact piece 80 provided for pressing the elastic part, it is possible to simplify the shape of the parts, And the malfunction rate at the time of operation can be remarkably reduced.

Further, the movable elastic terminal 50 is provided with an elastic reinforcing portion 54 for providing an elastic force so as to maintain the adhesion with the switching terminal 30 for a long period of time during the seesaw motion. Therefore, even if the width of the movable elastic terminal 50 is narrower than that of the conventional case, the thickness of the side wall part of the case part 10 can be maintained with respect to the narrowed mounting space k. As a result, it is possible to provide a compact product in which the insulation performance and structural safety are guaranteed and the space required for installation is minimized. In addition, as the degree of freedom of design change with respect to the width of the case 10 in the front-rear direction is increased, a highly compatible product that can be applied to a European style housing having a square switch space can be provided.

In addition, since the light emitting circuit portion 70 is provided, the position where the switching device 100 is installed and the on / off state of the electric device connected thereto can be visually and easily confirmed even in a dark space.
